Image Resizer

Giới thiệu về Image Resizer

The Image Resizer lets you change the pixel dimensions of your photos and graphics instantly, right in the browser. Whether you need to scale images down for email attachments, resize thumbnails for a web gallery, or prepare assets to meet a platform's exact dimension requirements, this tool handles it all without any software installation. You can resize by percentage (e.g., 50% to halve the dimensions), by a fixed target width, or by a fixed target height — the aspect ratio is always preserved automatically to prevent distortion. Batch mode lets you apply the same resize settings to up to 50 images at once, saving enormous time compared to doing each file individually. The original file format is preserved (JPEG stays JPEG, PNG stays PNG, WebP stays WebP), and you can download results one by one or as a single ZIP archive. Processing happens entirely on your device, so there are no file size limits imposed by server-side APIs and your images remain completely private.

3. Enter the target value using the slider (for percentage) or the number input (for pixel dimensions).
